How AI Content Detection Works
AI detectors analyze writing patterns. Rather than looking for specific words, they examine structural characteristics.
What the detector examines
- Sentence variation — Humans vary sentence length and structure more.
- Word predictability — AI text shows more predictable sequences.
- Phrase repetition — Repeated phrase distribution can signal authorship.
- Lexical diversity — Range of unique vocabulary provides another signal.
